VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 728,619, dated May 19, 1903. Applioation filed December 30, 1902, Serial No.137|l16. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIAM W..RosnN- FIELD, a citizen of the United Stat-es, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Vending-Machines, of which the following is a specification.

My invention relates to a coin released manually operated vending machine for small articles of merchandise, such as candies, and in predetermined quantities, with the object of simplifying, the construction of such devices, making more positive the operation of the parts, and preventing fraudulent use or repetitions.

In carrying out my invention I provide a case advantageously of metal and preferably including a hopper for receiving the articles, a retaining-case, a discharge-aperture and delivery-receptacle, acoin device, and apushbar. The operative mechanism comprises a scoop mounted upon a shaft and a crank and handle manually operated, a gravity-chute receiving the goods from the scoop and delivering the same upon a swinging platform, from which they pass to the discharge-aperture and delivery-receptacle. I employ devices holding those parts in a normally inoperative position except when a coin is inserted and the push-bar actuated so as to release said parts and permit of their manual operation. These latter parts are supported by a frame and comprise a hub on the main shaft, having cam portions and ratchet-teeth, a crank on the main shaft, a spring for-imparting a return movement, rocker-arms, a-

dog and a pawl pivoted within the frame,-the rocker-arms engaging the hub upon the main shaft, one of said rocker-arms being engaged by the dog and the pawl engaging the teeth of the hub in opposite directions, all of which parts and movements are hereinafter more particularly described.

In the drawings, Figure 1 is a front elevation and partial vertical section showing particularly the parts operated by the'handle upon the main shaft. Fig. 2 is a sectional plan at line 00 a: of Fig. 1, representing the various parts of my invention. Fig. 3 is a vertical section at y y, Fig. 2, through the case and an elevation of the devices actuated by theinsertion of the coin and movement of mechanism. Fig. 4 is a detached elevation of the devices shown in Fig. 3 in the position to which the same are brought by the operation of the push-bar. Fig. 5 is ar. elevation illustrating the relation of the hub upon the main shaft and the ratchet-teeth thereof with the pawl; and Fig dis a similar elevation of the' same parts, together with the dog, in the the mainshaft- This case is provided with a hopper 1), into which the candies or other goods are to be placed. From the lower portion of the hopper sai goods pass through an opening 19 into the retaining-case c, which is of circular form and is at one side provided with a discharge-aperture 1), between the side walls of which isa swinging platform a,

and beneath the delivery edge of which discharge-aperture b there is a delivery-receptacle d, discharging through the case into a cup portion (1.

represents acoin-slot and coin device, and t" a push-bar, and beneath the base or foundation a of the case a lock-drawer is shown as advantageously employed for receiving the money; but this and the coin-slot and coin device, as Well as the push-bar, form no necessary part of my present invention. -The swinging platform a is, as shown in Fig. 1, pivoted at the lower end and supported upon a cross-bar between the sides of the dischargereceptacle 1), and whilethis platform receives the goods and forms a practical continuation of the discharge-aperture b for a gravity delivery the said platform is adapted in the event of the case being overturned to swing up and close off the discharge-aperture, as in this event the free end will strike thetop of said aperture, and as the platform is of a width corresponding with the aperture the same will be entirely closed off to prevent the escape of the goods.

The shaftfpasses through the center of the push-bar for releasing the hand-operated the machine. On the outer end of the shaft and outside of the case is a crank e and handle e, by which the shaft may be rotated. Inside the case there is a scoop g, formed at the end of an arm, which arm is integral with a hub g, mounted upon the shaftf. A setscrew passes through this hub and into a recess in the shaft, which recess is a little longer circumferentially than required, so as to permit of a slight freedom in the movement of the scoop device with reference to the shaft. A gravity-chute h is at one end pivoted to a yoke h, and said chute is made with a rib 4, adapted to rest upon the said yoke, and this is provided with an arm extending to a hub upon the shaftf, and there is a bracket-arm f secured to a part of the case and through which the shaft passes, and this bracket-arm at its free end comes beneath the arm of the yoke, so as to hold said parts in a normal position of rest.

A spring 5, secured at one end to the retaining-case, is at the other end secured toa pin 6, connected to and projecting from the bar of the yoke h, and as the yoke h is loosely pivoted upon the shaft the tendency of this spring is to hold the same with force in the position shown in Figs. 1 and 2, where the arm of the yoke rests upon the bracketarm f, and between the bracket-arm and the hub of yoke I prefer to secure to the shaftf a spacing-hub. (Shown in Fig. 2.)

Outside of the retaining-case c and between the same and the outer case a and secured to the base a is a frame 70, having two rising arms or parts, through which one end of the main shaftf passes, said end being journaled in said frame. I provide a hub Z, pinned to the shaft f between the parts of the frame. This hub is a composite structure formed on one side with cam portions 7 and on the other side with ratchet-teeth 8, and on said shaft f, outside of said frame It, is a crank m, also keyed to the shaft and having a stop-lug 9, adapted to bear on the edge of the frame 70, and I provide a spring 10 (shown only in Fig. 2) at one end connected to said crank and at the other end to the base a*, and a part of said crank-hub may be advantageously grooved, so as to receive the convolutions of the spring 10 when the same is under tension.

I provide two short shafts 11 and 18 in the frame 70. Mounted on the shaft 11 are rockerarms no, the arm n having a tooth 13 and being heaviest at the right-hand end and having a spring 14 connected thereto at one end and at the other end to the frame 70. The

0 down and the left-hand ends up in engage ment with the cam-notch of the hub Z. The inclined portion of the rocker-arm .0 provides for the insertion between the right-hand ends of the rocker-arms of a device adapted to separate them, such as the push-bar t".

Pivoted on the shaft 18 is a dogrand a pawl s. The dog 1' is provided with a hook end to engage the tooth 13 of the rocker-arm n with a pin 15 from one side of the dog adapted to rest upon the surface of the frame and with a ing 16 projecting from the other side of the dog 1'; The pawl s has a squareended tooth adapted to engage the ratchetteeth 8 of the hub Z and an opposite end 3', having a sidewise lug or projection, and a spring 17 is at one end connected to said pawl and at the other end to the frame It.

The operation of the device is as follows: A coin is passed into the coin-slot 'i and into a coin-actuated device, which by its construction permits of the release and operation of the push-bar t". The inner end of this bar 1; with its inward movement passes up the incline of the rocker arm 0 and raises the rocker-arm n. This throws the tooth 13 beneath the hook end of, the dog 1' into the position Fig. 4, in which the rocker-arm n is held up at the righthand end and forced down at the left-hand end, so that this latter end is out of engagement with the cam of the hub l; but, as shown in Fig. 4, the end of the push-bar is between the rocker-arms, and the rocker-arm 0 is held down at the right-hand end and the left-hand end is held up still in engagement with the cam of the huh I, so that while inthe normal rest position of the parts,

Fig. 3, it is impossible to turn the shaft f by the crank e and handle 6' it is still in the position Fig. 4 also impossible to turn said parts. However, upon the return of said push-bar 1 to the normal position, Fig. 2, the rocker-arm o is released and its left-hand end falls by gravity to the position shown by dotted lines in Fig. 3, thus releasing the hub Z, so that the shaft f may now be turned by the crank e and handle e by hand. This movement swings the scoop g and by it a predetermined quantity of the goods in the retaining-case c, and when said scoop g rises to the first of the dotted positions shown in Fig. 1 a rib provided on the advancing edge of the arm thereof strikes upon the under side of the yoke h, and the further movement of the scoop also moves the yoke and the gravity-chute it against the action of the spring 5. As these parts progress with their movements the free end of the chute it passes over the surface of the swinging platform 0' and rests thereon, and the scoop rising above the chute delivers its contents of goods upon the chute and the same descend the chute by gravity to and over the platform a and down the discharge-aperture 1) into the delivery-receptacle d and therefrom into the cup portion d, where the goods may be taken away by hand. With this movement the I at a glance that this position of the ratchet teeth and the pawl prevents any backward movement of the parts and compels the entire movement to be made. At the end of the movement the pawl runs off the pawlteeth and the spring 17 returns the pawl sto the position Fig. 3. The spring 10 also comes in evidence at the end of the stroke to effect the return movement of the parts. In this return movement the crank m and the hub Z, with the shaft f, are moved in the direction of the arrow, Fig. 6, and with this movement the pawl s by engagement of the ratchetteeth 8 is brought into the opposite position, so that its end .9 is elevated and strikes the lug 16 of the dog 1', raises the dog r, and unhooks the tooth 13 of the rocker-arm n, so that said rocker-arm is brought down by the spring 14 until its left-hand end rests upon the cam-surface of the hub.

From the position Fig. 6 it will be noticed that here also a reverse movement is prevented and a complete return movement compelled, because while the tooth of the pawl engages the ratchet-teeth of the hub it is only possible to move it in one direction. At the end of the return movement the left-hand ends of the rocker-arms n 0 fall into the camnotch and the parts are again locked. The pawl sis returned to the position Fig. 3, ready to repeat the operations,and the dogrdescends by gravity, its hook end resting on the back face of the tooth 13, also ready to repeat the operations hereinbefore described. To further actuate the mechanism, it is not only necessary to insert another-coin, but to fully actuate the push-bar, and while the parts remain in this position it is also impossible to move the shaftf by the crank and handle 6 e, and consequently impossible to remove any of the small articles or candies from the receptacle. After the rocker-arm n is engaged by the tooth 13 and the push-bar t" removed and the machine started the rocker-arm 0 hangs by gravity in the position shown by dotted lines, Fig. 3, directly in the path of the push-bar 2', thus preventing any false or trick movements with reference to the apparatus or movements of the coin.

I do not herein limit myself to the use of the spring 10, for while the same is desirable yet the shaftf and connected parts can be returned by hand totheir original position. In my application for Letters Patent for improvementin coin-operated machines filed May 21, 1902, Serial No. 108,307, I have shown and described the coin device and push-bar preferably employed with the structure of my present invention.
